Answer:
Rocks which were underwater long time ago.
Explanation:
If we were hunting for trilobites in Canada, we look for those types of rocks where once water present on it because trilobites are the organisms which lived in the marine ecosystem so if they are present in marine so we have to look those rocks which were underwater millions of years ago. Trilobites are the extinct marine arthropods that were present around 521 million years ago.
The sort of rocks that will be looked at during hunt for trilobites in Canada is
in deep ocean floor.
Trilobites are referred to as marine invertebrates which went extinct and was
discovered in China in a layer of rock called Devonian Shale. Subsequent
search for them have been found in Limestone shales also.
Limestone shales have layers of limestone present and they can be found in
deep ocean floors, basins and floodplains. The trilobites however will most
likely be found in deep ocean floors as a result of them being fossilized.
